Clinical Trial Summary

We hypothesize that combining anti-PD1 treatment with radiotherapy might result in improved clinical response rates and PFS compared to anti-PD1 treatment in monotherapy.

The current phase II trial aims at exploring the suggested benefits of the combination and aims to improve local and distant tumour responses by exploiting the pro-immunogenic effects of radiotherapy in addition to anti-PD1 treatment.

Intervention

Radiation:
• stereotactic body radiotherapy
In patients with metastatic melanoma, anti-PD-1 treatment will be combined with stereotactic body radiotherapy (SBRT). A total dose of 24 Gy SBRT will be delivered in 3 fractions to one measurable lesion and fractions will be separated >48h and <96h.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Efficacy	Objective responses will be measured using RECIST v1.1. Objective responses will be defined as the number of patients with complete or partial responses as best response during follow-up.	12 weeks
Secondary	Immunologic responses	Immunologic responses will be assessed using peripheral blood samples, analyzed with FACS phenotyping, functional testing and ELISA.; Changes in immunological parameters in tissue will be analyzed using immunohistochemistry.	12 weeks
